Absorbent articles having colored regions are preferred by consumers for the benefits they provide. One benefit is that the colored region can help mask body fluids collected by the absorbent article, such as menses or urine. This ability to mask absorbed body fluids provides the user with an increased feeling of cleanliness and protects the undergarments from soiling. Another benefit is that the coloured zone in the second layer, especially in the central zone of the absorbent article where body fluid is mainly absorbed, also provides the user with a desired visual impression of depth. This perception of absorbent article depth increases the user's confidence in the absorbent capacity of the absorbent article, and thus in the successful absorption and storage of bodily fluids; thus reducing the likelihood of soiling the undergarment.
